VENTILATED SPRlNGw-S'EAT.

SPECIFICATION forming part of Letters Patent No.- 462,317, dated November 3, 1891.

Application filed March l0, 1891. Serial No. 384,504. (No model.)

To all whom t may concern.-

Be it known that l, JoEL W. KENFIELD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Ventilated Spring-Seats, of which the following is a specification, reference being had to the accompanying drawings, in which- 1o Figure l is a top or plan view, and Fig. 2 is a cross-section on line 2 2 ot' Fig. l.

My invention relates to portable spring cushions orseats which are adapted to be used as cushions upon springless seats of various I5 kinds.

The object of my invention is to provide an improved spring-seat which will present a sott and elastic seating-surface, willbelight and durable in construction, and will permit 2o the circulation ot' air throughout the body of the seat. I accomplish these objects as illustrated in the drawings and as hereinafter specified. That which I regard as new will be pointed out in the claim. Y

Inthe drawings, A, Fig. l, indica-tes aspringseat constructed after my improved pattern. The upper portion ot' the seat A consists of a leather seat, which is stretched upon a rectangular frame B, composed of strips of wood 3o or other suitable material, which strips are mortised or otherwise suitably secured together at the corners,which may be rounded, as shown, to better adapt the seat to tit into a chair or other article upon which it may be placed. Upon the strips B of the frame are placed pads c, over which the leather seatbottoin is tightly stretched. The seatbottom C- is fastened to the outer edges ot the strips composing the frame B. By this 4o construction the elasticity or spring of the seat-bottom is greatly increased. In order to permit of the passage of air through the seat-bottom C, it is perforated, as best shown in Fig l,which perforationsmay be arranged in some artistic design to add to the appearance of the seat. The lower panel D of the seat is also provided with perforations d, as best shown in Fig. 2, which construction permits of the escape of the inclosed air when 5o the seat is compressed.

E E indicate spiral springs, which are made of springwire and are shaped like a double cone, as shown in Fig. 2. The springs E are mounted at suitable points upon the portion D of the seat, as best shown by dotted lines in Fig. l, and are adapted to support the poi'- tion B, being so placed that their upper portions will bear against the under side of the strips B to hold them in the position shown in the drawings. rlhe space between the por- 6o tions B and D of the seat is inclosed by means of strips F,of leather or other suitable material, which are. secured to the edges of the portions B and D, as best shown in Fig. 2.

By the construction shown the cushion or seat A is rendered very sott and flexible, as the spring of the seat-bottom C on the frame B is combined with the elasticity of the springs E and ot the bottom I).

Owin to the lightness of the materials 7o used, the entire seat weighs but very little, and it may readily be transported for use wherever desired and is adapted for use as a cushion upon almost any kind'of an uncushioncd seat, and especially for use upon seats in theaters and other audience-halls. Then used for the latter purpose. the seat may be made a part of the chairand be permanently secured in place.

The above-deseribed construction also per- 8o mits of the free circulation of air throughout the seat, so that it is well adapted for use in warm weather or in warm rooms, as the seat cannot become heated, an objection which is common to the seats now usedin public halls generally.

That I claim as my invention, and desire to secure by Letters Patent, isl A spring cushion or seat consisting of a `perforated bottom panel D, an open rectan- 9o gular top frame B, connected with the bottom panel by flexible material, a series of spiral springs interposed between the perforated bottom panel and the top rectangular frame, the pads c, arranged upon the upper part oi' the top rectangular frame, and the perforated seat-covering C, extending over the pads and attached to the edges of the rectangular frame, substantially as shown and described.
